========================================================================== Ubuntu Security Notice USN-7793-5 October 08, 2025
linux-gke vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 22.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-gke: Linux kernel for Google Container Engine (GKE) systems Details: Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - Packet sockets; - Network traffic control; - VMware vSockets driver; (CVE-2025-38477, CVE-2025-38617, CVE-2025-38618) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS linux-image-5.15.0-1090-gke 5.15.0-1090.96 linux-image-gke 5.15.0.1090.89 linux-image-gke-5.15 5.15.0.1090.89 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
